These were the main changes in this cycle:
- LKMM updates: mostly documentation changes, but also some new litmus tests for atomic ops.
- KCSAN updates: the most important change is that GCC 11 now has all fixes in place
to support KCSAN, so GCC support can be enabled again. Also more annotations.
- futex updates: minor cleanups and simplifications
- seqlock updates: merge preparatory changes/cleanups for the 'associated locks' facilities.
- lockdep updates:
- simplify IRQ trace event handling
- add various new debug checks
- simplify header dependencies, split out <linux/lockdep_types.h>, decouple
lockdep from other low level headers some more
- fix NMI handling
- misc cleanups and smaller fixes

arm64 and cross-arch updates for 5.9:
- Removal of the tremendously unpopular read_barrier_depends() barrier,
which is a NOP on all architectures apart from Alpha, in favour of
allowing architectures to override READ_ONCE() and do whatever dance
they need to do to ensure address dependencies provide LOAD ->
LOAD/STORE ordering. This work also offers a potential solution if
compilers are shown to convert LOAD -> LOAD address dependencies into
control dependencies (e.g. under LTO), as weakly ordered architectures
will effectively be able to upgrade READ_ONCE() to smp_load_acquire().
The latter case is not used yet, but will be discussed further at LPC.
- Make the MSI/IOMMU input/output ID translation PCI agnostic, augment
the MSI/IOMMU ACPI/OF ID mapping APIs to accept an input ID
bus-specific parameter and apply the resulting changes to the device
ID space provided by the Freescale FSL bus.
- arm64 support for TLBI range operations and translation table level
hints (part of the ARMv8.4 architecture version).
- Time namespace support for arm64.
- Export the virtual and physical address sizes in vmcoreinfo for
makedumpfile and crash utilities.
- CPU feature handling cleanups and checks for programmer errors
(overlapping bit-fields).
- ACPI updates for arm64: disallow AML accesses to EFI code regions and
kernel memory.
- perf updates for arm64.
- Miscellaneous fixes and cleanups, most notably PLT counting
optimisation for module loading, recordmcount fix to ignore
relocations other than R_AARCH64_CALL26, CMA areas reserved for
gigantic pages on 16K and 64K configurations.
- Trivial typos, duplicate words.

Pull arm64 and cross-arch updates from Catalin Marinas:
"Here's a slightly wider-spread set of updates for 5.9.
Going outside the usual arch/arm64/ area is the removal of
read_barrier_depends() series from Will and the MSI/IOMMU ID
translation series from Lorenzo.
The notable arm64 updates include ARMv8.4 TLBI range operations and
translation level hint, time namespace support, and perf.
Summary:

barrier, which is a NOP on all architectures apart from Alpha, in

Pull unicore32 removal from Mike Rapoport:
"Remove unicore32 support.
The unicore32 port do not seem maintained for a long time now, there
is no upstream toolchain that can create unicore32 binaries and all
the links to prebuilt toolchains for unicore32 are dead. Even
compilers that were available are not supported by the kernel anymore.
Guenter Roeck says:
"I have stopped building unicore32 images since v4.19 since there is
no available compiler that is still supported by the kernel. I am
surprised that support for it has not been removed from the kernel"
However, it's worth pointing out two things:
- Guan Xuetao is still listed as maintainer and asked for the port to
be kept around the last time Arnd suggested removing it two years
ago. He promised that there would be compiler sources (presumably
llvm), but has not made those available since.
- https://github.com/gxt has patches to linux-4.9 and qemu-2.7, both
released in 2016, with patches dated early 2019. These patches
mainly restore a syscall ABI that was never part of mainline Linux
but apparently used in production. qemu-2.8 removed support for
that ABI and newer kernels (4.19+) can no longer be built with the
old toolchain, so apparently there will not be any future updates
to that git tree"

userfaultfd: simplify fault handling
Instead of waiting in a loop for the userfaultfd condition to become true, just wait once and return VM_FAULT_RETRY. We've already dropped the mmap lock, we know we can't really successfully handle the fault at this point and the caller will have to retry anyway. So there's no point in making the wait any more complicated than it needs to be - just schedule away. And once you don't have that complexity with explicit looping, you can also just lose all the 'userfaultfd_signal_pending()' complexity, because once we've set the correct process sleeping state, and don't loop, the act of scheduling itself will be checking if there are any pending signals before going to sleep. We can also drop the VM_FAULT_MAJOR games, since we'll be treating all retried faults as major soon anyway (series to regularize and share more of fault handling across architectures in a separate series by Peter Xu, and in the meantime we won't worry about the possible minor - I'll be here all week, try the veal - accounting difference).

fscrypt updates for 5.9
This release, we add support for inline encryption via the blk-crypto framework which was added in 5.8. Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt', the contents of encrypted files will be encrypted/decrypted via blk-crypto, instead of directly using the crypto API. This model allows taking advantage of the inline encryption hardware that is integrated into the UFS or eMMC host controllers on most mobile SoCs. Note that this is just an alternate implementation; the ciphertext written to disk stays the same. (This pull request does *not* include support for direct I/O on encrypted files, which blk-crypto makes possible, since that part is still being discussed.) Besides the above feature update, there are also a few fixes and cleanups, e.g. strengthening some memory barriers that may be too weak. All these patches have been in linux-next with no reported issues. I've also tested them with the fscrypt xfstests, as usual. It's also been tested that the inline encryption support works with the support for Qualcomm and Mediatek inline encryption hardware that will be in the scsi pull request for 5.9. Also, several SoC vendors are already using a previous, functionally equivalent version of these patches. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCXye2EBQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOK0veAQCKEnwvy+M6s2/QWhC9vo01rABMtt7h VRAAKPiFzLNH3AD/dCnZNsFUzk3x0ZyiU1YRW3FvlxFOaEO7Ea0Pt/pyyQ0= =g9FK -----END PGP SIGNATURE----- Merge tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fscrypt updates from Eric Biggers: "This release, we add support for inline encryption via the blk-crypto framework which was added in 5.8.

Pull btrfs updates from David Sterba:
"We don't have any big feature updates this time, there are lots of
small enhacements or fixes. A highlight perhaps is the parallel fsync
performance improvements, numbers below.
Regarding the dio/iomap that was reverted last time, the required API
changes are likely to land in the upcoming cycle, the btrfs part will
be updated afterwards.
User visible changes:
- new mount option rescue= to group all recovery-related mount
options so we don't have many specific options, currently
introducing only aliases for existing options, future extensions
are in development to allow read-only mount with partially damaged
structures:
- usebackuproot is an alias for rescue=usebackuproot
- nologreplay is an alias for rescue=nologreplay
- start deprecation of mount option inode_cache, removal scheduled to
v5.11
- removed deprecated mount options alloc_start and subvolrootid
- device stats corruption counter gets incremented when a checksum
mismatch is found
- qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id>
using sysfs
- add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated
backing dev info
- FS_INFO ioctl enhancements:
- add flags to request/describe newly added items
- new item: numeric checksum type and checksum size
- new item: generation
- new item: metadata_uuid
- seed device: with one new read-write device added, print the new
device information in /proc/mounts
- balance: detect cancellation by Ctrl-C in existing cancellation
points
Performance improvements:
- optimized versions of various helpers on little-endian
architectures, where we don't have to do LE/BE conversion from
on-disk format
- tree-log/fsync optimizations leading to lower max latency reported
by dbench, reduced by about 12%
- all chunk tree leaves are prefetched at mount time, can improve
mount time on large (terabyte-sized) filesystems
- speed up parallel fsync of files with reflinked/deduped extents,
with jobs 16 to 1024 the throughput gets improved roughly by 50% on
average and runtime decreased roughly by 30% on average, notable
outlier is 128 jobs with +121.2% on throughput and -54.6% runtime
- another speed up of parallel fsync, reduce number of checksum tree
lookups and contention, the improvements start to show up with 2
tasks with +20% throughput and -16% runtime up to 64 with +200%
throughput and -66% runtime
Core:
- umount-time qgroup leak checker
- qgroups
- add a way to unreserve partial range after failure, avoiding
some EDQUOT errors
- improved flushing logic when EDQUOT is hit
- possible EINTR interruption caused by failed reservations after
transaction start is better handled and documented
- transaction abort errors are unified to EROFS in case it's not the
original reason of abort or we don't have other way to determine
the reason
Fixes:
- make truncate succeed on a NOCOW file even if data space is
exhausted
- fix cancelling balance on filesystem with exhausted metadata space
- anon block device:
- preallocate anon bdev when subvolume is created to report
failure early
- shorten time the anon bdev id is allocated
- don't allocate anon bdev for internal roots
- minor memory leak in ref-verify
- refuse invalid combinations of compression and NOCOW file flags
- lockdep fixes, updating the device locks
- remove obsolete fallback logic for block group profile adjustments
when switching from 1 to more devices, causing allocation of
unwanted block groups
Other cleanups, refactoring, simplifications:
- conversions from struct inode to struct btrfs_inode in internal
functions
- removal of unused struct members"

mm: rewrite wait_on_page_bit_common() logic
It turns out that wait_on_page_bit_common() had several problems, ranging from just unfair behavioe due to re-queueing at the end of the wait queue when re-trying, and an outright bug that could result in missed wakeups (but probably never happened in practice). This rewrites the whole logic to avoid both issues, by simply moving the logic to check (and possibly take) the bit lock into the wakeup path instead. That makes everything much more straightforward, and means that we never need to re-queue the wait entry: if we get woken up, we'll be notified through WQ_FLAG_WOKEN, and the wait queue entry will have been removed, and everything will have been done for us.

Fourth batch of perf tooling fixes for v5.8:
- Fix libtraceevent build with binutils 2.35.
- Fix memory leak in process_dynamic_array_len in libtraceevent.
- Fix 'perf test 68' zstd compression for s390.
- Fix record failure when mixed with ARM SPE event.
Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
Test results:
The first ones are container based builds of tools/perf with and without libelf
support. Where clang is available, it is also used to build perf with/without
libelf, and building with LIBCLANGLLVM=1 (built-in clang) with gcc and clang
when clang and its devel libraries are installed.
The objtool and samples/bpf/ builds are disabled now that I'm switching from
using the sources in a local volume to fetching them from a http server to
build it inside the container, to make it easier to build in a container cluster.
Those will come back later.
Several are cross builds, the ones with -x-ARCH and the android one, and those
may not have all the features built, due to lack of multi-arch devel packages,
available and being used so far on just a few, like
debian:experimental-x-{arm64,mipsel}.
The 'perf test' one will perform a variety of tests exercising
tools/perf/util/, tools/lib/{bpf,traceevent,etc}, as well as run perf commands
with a variety of command line event specifications to then intercept the
sys_perf_event syscall to check that the perf_event_attr fields are set up as
expected, among a variety of other unit tests.
Then there is the 'make -C tools/perf build-test' ones, that build tools/perf/
with a variety of feature sets, exercising the build with an incomplete set of
features as well as with a complete one. It is planned to have it run on each
of the containers mentioned above, using some container orchestration
infrastructure. Get in contact if interested in helping having this in place.
Some of the most recent, experimental distros are failing, fixes will be
provided, but those gcc/clang versions are not yet in general use and some
are related to linking with libllvm, not the default build.

vxlan: fix memleak of fdb
When vxlan interface is deleted, all fdbs are deleted by vxlan_flush().
vxlan_flush() flushes fdbs but it doesn't delete fdb, which contains
all-zeros-mac because it is deleted by vxlan_uninit().
But vxlan_uninit() deletes only the fdb, which contains both all-zeros-mac
and default vni.
So, the fdb, which contains both all-zeros-mac and non-default vni
will not be deleted.
Test commands:
ip link add vxlan0 type vxlan dstport 4789 external
ip link set vxlan0 up
bridge fdb add to 00:00:00:00:00:00 dst 172.0.0.1 dev vxlan0 via lo \
src_vni 10000 self permanent
ip link del vxlan0
kmemleak reports as follows:

io_uring: flip if handling after io_setup_async_rw
As recently done with with send/recv, flip the if after
rw_verify_aread() in io_{read,write}() and tabulise left bits left.
This removes mispredicted by a compiler jump on the success/fast path.

kconfig: qconf: compile moc object separately
Currently, qconf.moc is included from qconf.cc but they can be compiled independently. When you modify qconf.cc, qconf.moc does not need recompiling. Rename qconf.moc to qconf-moc.cc, and split it out as an independent compilation unit. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

kconfig: qconf: use if_changed for qconf.moc rule
Regenerate qconf.moc when the moc command is changed. This also allows 'make mrproper' to clean it up. Previously, it was not cleaned up because 'clean-files += qconf.moc' was missing. Now 'make mrproper' correctly cleans it up because files listed in 'targets' are cleaned. Signed-off-by: Masahiro Yamada <masahiroy@kernel.org> |

From Xin Long. 2) Several fixes for the new ESP in TCP encapsulation. From Sabrina Dubroca. 3) Fix crash when the hold queue is used. The assumption that xdst->path and dst->child are not a NULL pointer only if dst->xfrm is not a NULL pointer is true with the exception of using the hold queue. Fix this by checking for hold queue usage before dereferencing xdst->path or dst->child. 4) Validate pfkey_dump parameter before sending them. From Mark Salyzyn. 5) Fix the location of the transport header with ESP in UDPv6 encapsulation. From Sabrina Dubroca. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

rds: Prevent kernel-infoleak in rds_notify_queue_get()
rds_notify_queue_get() is potentially copying uninitialized kernel stack
memory to userspace since the compiler may leave a 4-byte hole at the end
of `cmsg`.
In 2016 we tried to fix this issue by doing `= { 0 };` on `cmsg`, which
unfortunately does not always initialize that 4-byte hole. Fix it by using
memset() instead.
